Personally, I don't have any evidence of dishonesty. It is easy to see the trading history. Volumes are so low with most people following these forums that they would get called out by the real buyers if they were being dishonest.
I hope someday that the pumpers are right about something so the PPS goes up. It must be tough for them when jameshutchens10 from Stocktwits has a better track record of being right.
